IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent N0. 127,674, dated June 1 1, 1872; antedated June 5, 1372.

I, GEORGE BRADLEY, of Rockford, in the a county of Winnebago, in the State of Illinois,

have invented certain Improvements in Seed- Sowers and Cultivators, of which the following is a specification:

The object of this invention is to improve upon that contained in a patent issued to me July 5, 1870, numbered 104,926; and it consists in the construction of some of the parts of the implement and their arrangement with others of which the machine is constructed, as is more fully hereinafter described.

In the drawing, Figure 1 is a top or plan view of the machine. Fig. 2 is a side view. Fig. 3 is a rear-end view. Fig. 4 is a section of the seed-box and its internal devices; Fig.

, 5, a transverse View; and Fig. 6, a side view of the same. Fig. 7 shows the plates by which the plow-standards are attached to their beams, and Fig. 8 a modification of the same.

A is the ordinary arched axle upon which the frame and parts of the machine are supported. B is the wheels that revolve on axle A. G is the frame bolted to the axle A and fast to the tongue. D is the tongue firmly attached to frame 0, and by which the machine is drawn forward. E is the frame carrying the plow-standards E and plows E, which are suspended and held in position at its forward end by means of the angle-bracket g, screwrod 9, and pendants g, the pendants 9 being fast and depending from the under side of a cross-girt of the frame 0 and the angle-bracket fast on the top of the frame E, having a part vertical, through which and the pendants 9 goes the screw-rod 9, having nuts g at each end and on the outside of pendants g, which are placed at some distance apart, and having bracket 9 between them allows of a lateral movement of the bracket 9 and the frame E, to which it is attached, and at its rear end by chains 9 attached to frame E by eyes or staples, and thence going up over segmentwheels 0 to which the other end of chain 9 is fixed, when, by operating lever 0 that is pivoted onto shaft 0, the wheel 6 is made, through chain 9 to either raise or lower the rear end of frame E, and is held in position by a spring-bolt attached to lever 0 catching into notches in notched arch e? in the usual way. E E are arched yokes, with screwand its plows to the right or left, a lever, e, is pivoted near its center of length to bracket e on frame 0, with a connecting-rod or link, 0 attached to the yoke E, or to the vertical part of bracket 9, while its rear end is in easy reach of the driver on seat 0. The plowstandardsE are attached to the beams of frame E by means of plates I and I and bolts i- Plate I is made to have a concave part, i, while plate I has a convex projection, i, to fit into the concave part of plate I, and in its outer end is a recess, 1', of some depth to receive the standard E of the plows E. The concave and convex surfaces of plates I and I that come in contact are corrugated in order to hold the standard easily and without so much strain on bolt 1' as would result if not so corrugated, as seen in Fig. 7 but these surfaces may be plain, as seen in Fig. 8, but I prefer them corrugated. This construction allows the plow-standards to be adjusted to have them stand vertical'or to any angle to a perpendicular position, or may be turned horizontally to give the plow more or less angle to the direction of the furrow, as may be desired, as it onlyrequires the holes in the plates I and I, to be enlarged at the point of meet ing, when a single bolt, with the adjustable draw-bar 0, will hold the standard in any desired position. H H are the pieces forming the harrow, which is drawn and suspended underneath the frame E'by means of the draw-rod h, that is hooked onto a hook on the top of the harrow and extends forward and upward, and

is attached to the under side of the tongue D, while its rear end is suspended by chains h that extend backward and rise to be attached to the under side of the rear end of frame E, by which construction the harrow can be attached to or detached from the frame E at will and by this mode of attaching and suspending the harrow is more thoroughly braced and held in its position than by any other known method in use.

The machine is drawn forward by means of hitching the tugs of the harness into hooks cl of the draft-levers d that pass upward through eyes or staples on double-tree d on the back sides of said levers d; and below the doubletree is attached draw-rods b that pass backward and are secured to clips b around the aXle-tree A.

I am aware of the patents granted to R. McGorkel August 4, 1868 John S. Hall, August 14, 1860; and Barns and Jamison, January 31, 1871; and I disclaim the devices therein plate I having the corrugated convex surface i and bolt 2", in combination with the plowstandards E and beams of frame E constructed and arranged as described.
